LAMP RECEPTACLE Filed June 16, 1950 Ill-liliiiiiim names /N VEN TOF w/T/vsss @Y MWA r/ the passage therethrough of insulated wires 3 such as are ordinarily provided for connecting a weatherproof receptacle to the line, the boss 2 being provided with external screw threads 4 nhich may desirably be one-half inch pipe threads. For convenience and economy in manufacture and to avoid a joint between the boss and the shell of the receptacle, I prefer to form the shell and the boss as an integral molded unit. The wires 3, as well as the usual metallic threaded sleeve and other parts associated therewith through which connection between the electric light' and wires is effected in the customary way,

may be positioned in the mold at the time the receptacle is made, and are thereafter securely maintained in proper position within the boss by the Bakelite7 or other material eml ployed, and a weather and moisture proof joint is thereby made between the boss and the insulating covering of the wires. Additionally, I prefer to form the threads 4 simultaneously with `the molding operation, and it will be understood that the mold is therefore preferably provided with theproper internal threads to effect this result.V

The boss is adapted to receive means operative to serve as a handle for the receptacle or to form a fixed support therefor depending upon the particular use to which the receptacle is to be put. Thus when the receptacle is to be used in connection with a flexible cord, as shown in Figs. 2 and 3, I mayy provide, to form a convenient handle, a piece of ordinary hose 5, which may desirably be externally corrugated as shown, of proper diameter to receive the boss 2, and of suitable length.

As will be best understood from reference to Fig. 3, when assembling the parts underthese conditions, the hose is first slipped over and along the flexibleextension cord 6 far' enough to expose the endof the latter and ployed to individually protect the spliced' the wires 3 then spliced to the conductors 7 thereofvin the usual manner, tape 8 being emjoints which need not be thereafter taped together.

boss 2, an operation which may be very easily vperformed as the threads 4 readily cut suitable complementary threads in the inner wall of the hose, thus firmly securing these parts together.

IVhen thus assembled, it is apparentthat the hose 5 serves as a handle for the receptacle and, although flexible to a limited extent, nevertheless protects the splice from undue bending, wear or other factors tending either to. break the conductors at this point or expose their surfaces whereby the dangers 'attend-` ant upon such breakage or exposure are entirely avoided. Moreover, the joint formed.' between the hose and the receptacle is water and-damp proof which is of material advanrIhe hose is then slipped downv over` the splice and'screwed onto the end of theVv one of them for .any reason should become broken or exposed insulating material.

My. improved receptacle. may also'be employed in stationary or fixed installations, for example by connecting it through the medium of a pipe coupling l0 with a rigid, conduit 1l in which are disposed line wires l2 as shown in Fig. 4, the coupling being interposed between and screwed upon the boss and the end oftheconduit, or may be `utilized in through its covering of numerous other ways in various sorts of elec-'3L trical installations-as Will be readily apparent to those familiar therewith. IfVhile I have herein shown and described a preferred form of the invention with some particularly, I do not thereby desire or intend to confine myself specifically thereto as the shell of the receptacle may be ofany desired form-and the kind andf size of the threads or other fastening upon the bosslnay be varied as desired, and/or other modilicaiilo@ tions and changes made in the details of design and construction without departing from the spirit and scope of. the invention as defined in ther appended claims.

Having thus described `my invention. *I*

claim and desirev to protect by Letters Patent of the United States: l

i 1. A weatherproof lampA receptaclecom.- prising a molded hollow shell adapted to receive the lbase of an integrally molded 'therewith' a yrearwardly extending boss of'smalle'r diametertha'n the shell adapted-for interconnection with means for supporting the receptacle, anda pair of viresextending through and molded intoithe' lboss for connecting the receptacleto a` current source. j

. 2.A weatherproof lamp receptacle comprising a molded shell adapted to receive the base of an electric light and having integrally molded therewith a'rewardly extending boss adapted for interconnection withmeans for supporting the receptacle,' and Wires leading through and molded into the boss for connecting the receptacle to a current source.

B. A vweatherproof lamp receptacle comprising a moldedshell adapted to receive at one end the base Aof an 'electric light and hav- -ing an integral externally threadedA boss extending from its other end, and wires leading electric light and having-1 through and sealed in said bo's's for connecting the receptacle to a. current Source.

4. A weatherproof lamp receptacle comrising a molded shell adapted to receive the ase of an electric light and having a rea-rwardly extending boss adapted for intercom nection with means for supporting the receptacle, and Wires leading through and sealed in the boss for connecting the receptacle to a current source.

In witness whereof I have hereunto set my hand this 13 day of June, 1930.
